IMPROV'EDENT 1N THE CONBTUCTIQN OP CONVERTERS AND F'U'RIACES'QEOR TREAT- ING- IRON DTHER METALS.

The Schedule referred to in than Letton Patent and making ofthe'nml.

To all whom it may cozwcrm' Be it known that I, J OHX Anstmnnm, ofthe city, county, and State of New York, have invented a. new and useful Improvement in the Construction of Gonverters, and other Furnaces; and I do hereby declare the following to be a full, clear, and exact description thereof', suicient to enable those skilled in the alt to which my invention appcrtains, to fully understandand use thesame, reference being had to the accompany ing drawings, forming part oi' this specification, and in which Figures 1, 3,'anii 5, are top views, and

Figures 2, 4, and 6, are vertical sections of figs. 1, 3, and 5, respectively.

`My invention relates to the construct-ion of couverters, and other furnaces, and is an improvement in the mode of constructing the fire-walls ofsucli furnaces.

It consists in constructing such walls in sections or segments, so formed as to interlock, one with another,

so as t0 constitute a very solid wall, which can be built in a sliort'tilne, as vll hereinafter be'fully described.

Similar letters of reference indicate corresponding parts in the several figures ofthe drawings.

I construct the fire-walls in sections, A A, of some reiiawr'y material, as that, for instance, of which ordinary tire-bricks or crucibles are nade.

4These sections may be formed,- as shown in figs. l and 2, with' a rounded bead, a, on the upper side, and afcorresponding concavity on the under side, adapted to receive the bead ofthe section below.

The bead a and the wrrespouding concave groove b extend entirely around the'section, following the curve ofthe same.

Y In igs. 3 and 4, I have shown the sections made with the upper surface convex from side to side, and

Y the under surface in the same manner made concave,.

to iit the upper surface of the section next below.

Figs. 5 and 6 represent the sections formed with a square bead, c, on top, and a corresponding groove in the under side.

In fig. 1, I have shown three forms of joints for securing the sections together at their ends.

It will be observed that the joint e is formed vby a projecting rounded bead entering a corresponding coucavity; At f the bead is square, and at g, the end of one section is made convex to t 'the concave end of that adjoining. 1t will thus be seen that the ends of the sections are formed like the upper and under sides of the same. Y

In constructinga wall with my sections, I place 'them,one on top the other, so as tobreak joints.

The ends being interlocked, the sections are prelvented from either lateral or longitudinal movement,

and a solid, self-sustainingfstructure is produced.

I do not confine myself to the joints which are shown for interlocking the ends of the sections, nor tothe-precise construction of the upper and under .sides'of the sections themselves, as I am aware that these may be varied without departing from the principle of niy invention. v

Having thus described my invention,

What I claim as new, and desire to secure by Let ters Patent, is-

Constructing the walls of converters and other fur#` naces of separate sections or segments, so formed as to interlock, one with another, substantially as herein described and represented.
